Ok, so I haven't read through all the threads and just got home from work to actually get reliably info on this storm. Am I right that the winds and surge were'nt as catastrophic as expected?

Watching the news, everything seems calm in the places they're reporting from. Are they just away from the worst of it right now?

The rain has always been the concern. The wind was as expected from a Cat 4, but it doesn't last long.

What about the surge? That usually brings the most damage and I haven't heard anything about it.

I don't live near the coast so not sure if it means much but TV just said it's low tide now.

Looking quickly at a couple tide gauges (PTAT2 and RCPT2), it doesn't seem like the surge was particularly impressive. I posted yesterday that because the storm blew up so quickly that the surge wouldn't have time to ramp up like it does on most large storms, so we could be seeing a lower than expected surge amount. Hopefully that was the case?

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 400 AM CDT (0900 UTC), the eye of Hurricane Harvey was located
by NOAA Doppler radar near latitude 28.5 North, longitude 97.2 West.
Harvey is moving toward the northwest near 6 mph (9 km/h). Harvey
is expected to slow down through the day and meander over
southeastern Texas through the middle of next week.

Doppler radar data indicate that maximum sustained winds have
decreased to near 100 mph (155 km/h) with higher gusts. Additional
weakening is forecast, and Harvey is likely to become a tropical
storm later today.

Hurricane-force winds extend outward up to 35 miles (55 km) from the
center, and tropical-storm-force winds extend outward up to 140
miles (220 km).

The estimated minimum central pressure is 963 mb (28.44 inches).

Almost 10 inches of rain have already been reported at a few
locations in southeastern Texas.

more low surge totals. That's some good news out of Harvey

cat 4 storms are baseline correlated with 13-18 feet of storm surge.. but storm surge has a lot of factors, including size of storm and time spent at intensity.
